Use of LAN (Local Area Network) Technology in DSCS (Defense Satellite Communication System) Earth Terminals

摘要

The report addresses the use of local area network (LAN) technology to support intercommunications within the Defense Satellite Communications Systems (DSCS) earth terminals. A summary of local area network capabilities and options is provided as background material. Two types of device intercommunications are identified: the intercommunication of equipment to directly provide the circuit-switched channels needed for DSCS user circuits and the intercommunication of equipment in support of control and status monitoring functions. Issues and concerns regarding the application of LAN technology to either of these objectives are discussed. Additionally, the application of digital switching technology---specifically, use of the Integrated Multiplex, Patch, and Test (IMPAT) equipment---has also been considered as a means to fulfill these intercommunication requirements. Keywords include: Local Area Networks; Earth Terminals, and Defense Satellite Communication Systems (DSCS).
